So on the topic of Spiderman’s origin (the latest MCU iteration of Spiderman, the one Tom Holland plays) I’m pretty sure he’s sort of like a combination of the Spiderman from The Amazing Spiderman movies and the classic 3 Spiderman movies. He still has the spider sense, which we can assume is from the bite of the radioactive spider, but he can’t shoot webs on his own and creates a fluid that creates a web-like substance with super tensile strength which he can shoot using the little attachments to his wrists.

He can still climb walls and has enhanced strength, vision and agility as a result of the bite, he just lacks the ability to create webs naturally,

But he’s Spider-Man so he has to have webs.

The thing is,

It would be weird for organic webbing to come out of his hands.

It should come out of his ass or his dick. Like actual spiders.

And if it comes out of his dick, it would basically be cum.

And we never see Spider-Man cumming in the movies.

Leading me to believe:

MCU Spider-Man actually DOES have organic webbing, but, it only comes out of his dick when he cums.
